Kristen Stewart wore shades and a hoodie and was surrounded by security this afternoon when she touched down at LAX. The actress, who has been busy shooting Breaking Dawn for the last few weeks, also sported a new accessory — her wrist was in a splint! Hopefully she's OK to resume filming soon, since she's expected in Vancouver next week to continue working alongside her costars Robert Pattinson and Taylor Lautner. Robert, though, may have to leave Canada temporarily on the 27th if he joins his fellow A-listers at the Oscars as rumored. It seems to be Robert's turn at the Academy Awards, as it was Kristen who made a cameo in 2010.
